Abstract
A smoking article in the form of a filter cigarette can have adjustable air dilution provided by alignment of perforations in the paper wrap of the tobacco rod, a band circumscribing the rod, and the tipping paper. The band is attached to the rod and the tipping is movable relative thereto. Perforations extending about a portion of the circumferential distance around the smoking article allow the user to adjust the setting to low or high air dilution.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1. A filter cigarette comprising in combination a rod of smokable material, an axially aligned filter plug adjacent one end of the rod, and substantially air impermeable tipping material circumscribing and being fixedly attached to the filter plug and circumscribing a portion of the rod in the region adjacent the filter plug; said cigarette further comprising first and second bands in an end-to-end relationship, said bands circumscribing the rod in the region adjacent the filter plug and being disposed in and substantially filling the transverse region between the outer surface of the rod and the inner surface of the tipping material; the first band being constructed from a substantially air impermeable material and is fixedly attached to the rod in the region adjacent the filter plug; said first band comprising a substantially air impermeable region extending circumferentially about a portion of the circumferential distance around the rod, and said first band and underlying portion of the rod comprising an air permeable region extending circumferentially about a portion of the circumferential distance around the rod; the second band being positioned adjacent the first band towards the fire end of the cigarette and the outer surface thereof is fixedly attached to the inner surface of the tipping material which overlies said band; the tipping material comprising an air permeable region in the region therein which overlies the air permeable region of the first band; wherein axial rotation of the filter end of the cigarette relative to the rod varies the degree of radial alignment between the air permeable region of the tipping material and the air permeable region of the first band.
2. The filter cigarette of claim 1 wherein the material of said first band, said second band and said tipping material is paper, and the regions of air permeability is provided by a series of perforations therein.
3. The filter cigarette of claim 2 wherein said rod of smokable material comprises a smokable material contained in a wrapping material, wherein said wrapping material is paper having a region of air permeability in the region therein which underlies the perforations in the first band and tipping material.
4. The filter cigarette of claim 1 wherein each of said first and second bands are in a substantially abutting end-to-end relationship.Cited by (0)
